ANALYSES  OF  PARIS  GREEN  AND  LEAD  ARSENATE. 

By   GEORGE    E.   COLBY. 


The  present  bulletin  is  a  report  upon  the  operation  of  the  follow- 
ing' law : 

AN  ACT 

To  Prevent  Fraud  in  the  Sale  of  Parts  Green  Used  as  an  Insecticide. 

The  People   of   the   State   of   California,   represented   in    Senate   and   Assembly,    do 

enact   as   folloivs: 

Section  1.  It  shall  be  the  duty  of  each  and  every  manufacturer  of  paris  green 
(commercial  aceto-arsenite  of  copper)  to  be  used  as  an  insecticide  within  this 
State,  and  of  every  dealer  in  original  packages  of  said  paris  green  manufactured 
outside  of  this  State,  before  the  said  paris  green  is  offered  or  exposed  for  sale, 
or  sold  within  this  State  as  an  insecticide,  to  submit  to  the  Director  of  the 
California  Agricultural  Experiment  Station  at  Berkeley,  samples  of  said  paris 
green,  and  a  written  or  printed  statement  setting  forth  :  first,  the  brands  of  said 
paris  green  to  be  sold,  the  number  of  pounds  contained  in  each  package  in  which 
it  is  put  on  the  market  for  sale,  the  name  or  names  of  the  manufacturers  and  the 
place  of  manufacturing  the  same ;  second,  the  statement  shall  set  forth  the  amount 
of  combined  arsenic  which  the  said  paris  green  contains,  and  the  statement  so 
furnished  shall  be  considered  as  constituting  a  guarantee  to  the  purchaser  that 
every  package  of  such  paris  green  contains  not  less  than  the  amount  of  combined 
arsenic  set   forth   in   the   statement. 

Sec  2.  Every  purchaser  of  said  paris  green  in  original  packages,  which  is  manu- 
factured outside  of  this  State,  who  intends  to  sell  or  expose  the  same  for  sale,  and 
every  manufacturer  of  said  paris  green  within  this  State,  shall,  after  filing  the 
statement  above  provided  for,  with  the  Director  of  the  California  Agricultural 
Experiment  Station  at  Berkeley,  receive  from  the  said  Director  a  certificate  stating 
that  he  has  complied  with  the  foregoing  statement,  which  certificate  shall  be 
furnished  without  charge  therefor ;  said  certificate  when  furnished  shall  authorize 
the  party  when  receiving  the  same  to  deal  in  this  State  in  the  said  paris  green. 
Any  person  who  fails  to  comply  with  the  terms  of  section  one  of  this  Act  shall 
not  be  entitled  to  such  certificate  and  shall  not  be  entitled  to  deal  in  said  paris 
green  within  this  State.  Nothing  in  this  section  shall  be  construed  as  applying 
to  retail  dealers  selling  said  paris  green  which  has  already  been  labeled  and 
guaranteed. 

Sec  3.  Paris  green,  when  sold,  offered  or  exposed  for  sale,  as  an  insecticide,  in 
this  State,  shall  contain  at  least  fifty  per  centum  of  arsenious  oxide  and  shall 
not  contain  more  than  four  per  centum  of  the  same  in  the  uncombined  state. 

Sec  4.  The  Director  of  the  California  State  Agricultural  Station  at  Berkeley 
shall  examine  or  cause  to  be  examined  different  brands  of  paris  green  sold,  offered 
or  exposed  for  sale  within  the  State,  and  cause  samples  of  the  same  to  be 
analyzed,  and  shall  report  results  of  analyses  forthwith  to  the  Secretary  of  the 
State  Board  of  Horticulture  and  to  the  party  or  parties  submitting  said  samples, 
and  such  report  shall  be  final  as  regards  its  quality. 


178  UNIVERSITY    OF    CALIFORNIA— EXPERIMENT   STATION. 

Sec.  5.  Any  person  or  persons,  firm,  association,  company  or  corporation  violat- 
ing any  of  Hie  provisions  of  this  Act,  and  any  person  who  shall  sell  any  package 
of  paris  green  or  any  part  thereof  which  has  not  been  labeled  as  la-rein  provided, 
shall  be  guilty  of  a  misdemeanor,  and  shall  be  fined  not  less  than  fifty  dollars  nor 
more  than  two  hundred  dollars,  together  with  the  costs  of  the  suit  in  an  action 
caused  to  be  brought  by  the  State  Board  of  Horticulture  through  its  secretary  in  the 
name  of  the  people  of  the   State  of  California. 

Sec.  (>.  The  Attorney-General  of  the  State  of  California  is  charged  with  the 
prosecution  of  all  such  suits. 

Sec.    7.     This    Act    shall    take    effect    immediately. 

[February  28,   1901,  became  a   law  by  constitutional   limitation.] 

In  accordance  with  the  requirements  of  the  law  above  quoted  the 
Station  has  examined,  during  the  years  1904  and  1905  and  1905  and 
1906,  a  total  of  sixteen  dealer's  lots  of  paris  green,  nine  for  1904-1905 
and  seven  for  1905-1906;  comprising  a  total  of  43,070  pounds  paris 
green  tested  for  the  two  years  in  question. 

The  dealers  to  whom  certificates  were  issued  during  the  two  years 
are  as  follows:  Bean  Spray  Pump  Co.,  San  Jose,  Cal.;  AV.  P.  Fuller 
&  Co.,  San  Francisco,  Cal.;  Western  Drug  Co.,  Los  Angeles,  Cal.; 
Alack  &  Co.,  San  Francisco,  Cal. ;  Langley  &  Michaels  Co.,  San  Francisco, 
.Cal.;  Yates  &  Co.,  San  Francisco,  Cal.;  Kirk,  Geary  &  Co.,  Sacramento, 
Cal. 

The  names  of  the  manufacturers  of  these  goods  are  given  in  the 
table  of  results  of  examination  of  samples. 

One  certificate  was  denied,  viz.,  that  relating  to  2,000  pounds  of 
"Lion'  brand  of  paris  green,  manufactured  by  James  A.  Blanchard 
&  Co.,  New  York,  offered  to  W.  P.  Fuller  &  Co.,  San  Francisco,  Cal. 

Bulletin  No.  151,  "Arsenical  Insecticides,'  contains  information 
regarding  the  composition  of  paris  green  and  other  arsenicals  tested 
here  up  to  the  year  1904. 

The  following  table  shows  the  quantity,  in  tons,  of  paris  green 
tested  since  the  law  of  1901  went  into  effect;  also,  the  quantities  found 
passable  and  the  amounts  rejected: 

First  Seeond  Third  Fourth 

Year.  Year.  Year.  Year. 

Number  of  tons  examined .-  19  29.5  14.2  7.6 

Number  of  tons  refused 5  1.5  None.  1.0 

Number  of  tons  passable  (for  wbich  certiticates 
wereissued) ...14  28.0  14.2  (5.6 

It  appears  from  the  above  statement  that  up  to  the  end  of  the 
third  year  of  the  operation  of  the  California  law  governing  the  sale 
of  paris  green  great  improvement  was  had  in  the  quality  of  greens 
offered  for  sale  through  dealers  here,  and  shows  how  care  in  the 
manufacture  of  this  article  in  New  York  prevailed  as  against  the 
loose  methods  followed  in  earlier  times,  where  we  found  only  about 
20  per  cent  of  their  goods  passable.     But  in  the  fourtli   year  of  the 


ANALYSES  OF  PARIS  GREEN  AND  LEAD  ARSENATE.  179 

life  of  the  law  nearly  one  seventh  of  the  whole  of  the  paris  green  sub- 
mitted here  in  accordance  with  the  law  had  to  be  refused.  Thus,  the 
necessity  for  the  law  of  1901  becomes  emphatically  proved,  and  it 
should  be  upheld.  The  dealers  have,  in  the  last  year,  not  ordered  from 
New  York  as  much  paris  green  as  formerly ;  this  may  be  explained  by 
the  fact  that  certain  large  districts  of  the  State  have,  upon  the 
recommendation  of  this  Station,*  been  ordering  and  using  large  ship- 
ments of  lead  arsenate  as  a  preferable  article  to  destroy  the  codling- 
moth. 

Composition  of  Paris  Green. — Pure  paris  green  is  a  compound  of 
verdigris  (18  parts)  and  arsenite  of  copper  (82  parts),  so  combined 
as  to  form  aceto-arsenite  of  copper,  which  may  be  best  represented  by 
the  following  components:  copper  oxid,  31.29  per  cent;  arsenious  oxid 
(As2G..),  58.65  per  cent;  and  acetic  acid,  10.06  per  cent,  since  so  far 
a  chemical  formula  for  it  has  not  been  accepted.  Pure  paris  green 
does  not  contain  arsenious  oxid  as  such;  i.  e..  in  a  free  condition  it  is 
combined  with  copper,  and  a  microscopic  examination  of  paris  green 
should  not  show  that  the  particles  of  green  have  any  projecting 
crystals  of  free  white  arsenic  (As203)  or  even  remnants  of  octahedrals 
scattered  through  the  material.  Sometimes  a  little  sulfate  of  sodium 
(glauber  salt)  is  left  in  paris  green,  but  this  is  simply  due  to  poor 
work  in  manufacture— it  was  not  washed  out. 

I  aspect  ion  of  Invoices  of  Paris  Green.  —  The  lots  or  shipments  tested 
for  dealers  here  have  been  carefully  examined  as  to  weight  by  compe- 
tent representatives  of  the  Station,  and  in  no  case  were  there  any  dis- 
crepancies found.  The  buyer,  however,  has  to  satisfy  himself  that 
he  gets  full  weight,  especially  of  small  packages,  which  we  have  many 
times  found  to  be  a  little  short  in  weight ;  but,  like  anything  put  up 
in  containers,  the  shortage  usually  comes  to  nothing  more  than  the 
weight  of  the  paper  or  wood. 

The  chemical  tests  made  at  this  Station  comprise  those  relating  to 
the  total  poison  (As20;?  in  all  forms)  and  the  free,  or  uncombined 
(water-soluble),  arsenious  oxid.

1S2  UNIVERSITY    OF   CALIFORNIA —EXPERIMENT   STATION. 

Total  Arsenious  Oxid. — All  of  the  samples  examined  (representing, 
as  above  noted  for  1904-1906,  20.8  tons  green)  showed  upwards  of  50 
per  cent  of  total  arsenious  oxid — the  range  being  from  53.5  to  57.8 
of  tin1  material— not  as  great  as  formerly,  but  it  is  to  be  noted  that 
one  factory  turned  out  a  major  part  of  the  goods  sent  to  California. 
However,  it  appears  from  this  standpoint  that  we  have  not  been 
receiving  any  better  goods  than  those  last  reported,  and  certainly  not 
up  to  those  offered  to  New  York  and  New  Jersey  horticulturists. 

Water-soluble  Arsenious  Oxid  (common  white  arsenic).  —  The  method 
of  determining  this  ingredient  is  given  on  page  19  of  Bulletin  No.  151 
of  this  Station,  and  in  some  respects  differs  from  that  followed  at  the 
New  York  and  New  Jersey  stations ;  but,  as  far  as  practical  results  go, 
serves  what  was  intended,  viz.,  to  show  with  accuracy  what  might  be 
expected  as  regards  effect  on  foliage. 

It  seems  fair  yet  to  compare  again  the  water-soluble  arsenic  com- 
pounds found  in  paris  greens  offered  for  sale  in  the  samples  examined 
before  the  law  went  into  effect  with  those  tested  afterwards.  Before 
the  law  was  made  we  found  only  one  fifth  of  the  greens  collected 
throughout  the  State  to  be  satisfactory,  passable  for  use  in  this  State ; 
since  then  they  showed  a  wide  range  in  this  impurity,  or  from  as  little 
as  4.14  per  cent  to  as  much  as  29.40  per  cent.  After  the  law  became 
operative  this  range  in  difference  immediately  lessened,  so  that  only 
10  or  11  per  cent  was  determined  to  be  the  maximum  quantity,  and 
latterly  this  has  fallen  to  7.7  per  cent,  and  nearly  95  per  cent  of  the 
goods  tested  at  this  Station  do  not  reach  the  maximum  amount  per- 
missible, viz.,  4  per  cent  of  water-soluble  arsenious  oxid. 

SUMMARY   RELATING   TO   PARIS   GREEN. 

The  quality  of  paris  green  offered  by  dealers  and  examined  at  this 
Station  during  1904-1906  is  slightly  better  than  that  received  in 
California  for  insecticide  work  in  former  years.  But  at  no  time  since 
the  law  went  into  effect  has  any  gross  adulteration  been  detected. 

Every  dealer  in  paris  green  has  received  (as  far  as  has  been  ascer- 
tained by  examination)  from  the  manufacturers  during  the  last  two 
years  the  required  amount  of  poison  (As20:!)  in  these  goods  offered  as 
insecticides. 

The  water-soluble  arsenious  compounds  in  the  goods  tested  in  the 
third  year  did  not  amount,  in  any  invoice  of  paris  green,  to  enough 
to  cause  the  refusal  of  the  article,  and  of  20.8  tons  tested  during 
1904-1906  only  one  ton  was  refused  on  account  of  containing  over  4 
per  cent  of  water-soluble  arsenious  oxid. 

That  the  law  is  not  stringent  and  does  not  work  any  hardship  upon 
any  one  concerned  is  proven  by  the  facts  above  stated,  also  by  reason 


ANALYSES  OF  PARIS  GREEN  AND  LEAD  ARSENATE. 


is:; 


of  the  fact  that  no  complaints  have  been  lodged  against   it   since   it 
went  into  operation. 


ANALYSES    OF    COMMERCIAL    LEAD    ARSENATES. 

A  few  samples  of  these  excellent  spraying  materials  have  been 
tested,  and  all  have  been  found  to  contain  very  little,  if  any,  water- 
soluble  arsenions  compounds,  i.  e.  leaf-bnrning  compounds.  They  are 
true  to  label,  none  having  any  arsenites  in  them.  The  following  table 
gives  the  results  of  the  chemical  tests:

These  Eastern-made  lead  arsenates  come  into  this  market  mostly 
in  the  form  of  pastes,  which  are  easy  to  make  up  into  sprays.  They 
remain  long  in  suspension  in  the  spray-tank — very  much  longer  than 
paris  green.  However,  the  transportation  of  so  much  water  as  they 
ordinarily  hold  makes  them  expensive.  It  is  said  that  certain  districts 
here  have  undertaken  on  a  large  scale  to  provide  themselves  with  this 
valuable  material,  but  none  of  their  output  has  as  yet  been  sent  to  or 
obtained  by  the  Station  for  chemical  examination. 


184  UNIVERSITY   OF   CALIFORNIA.  — EXPERIMENT   STATION. 


PROPOSED  INSECTICIDE  CONTROL  LAW. 

By  C.   W.   WOODWORTH. 


The  preceding  article  by  Professor  Colby  has  shown  very  conclusively 
the  necessity  of  some  legal  regulation  of  the  sale  of  insecticides  in  this 
State.  This  is  in  the  interest  both  of  the  honest  dealer  and  of  the 
grower. 

The  present  law  is  intended  to  regulate  the  sale  of  but  a  single  in- 
secticide, paris  green,  and  this  substance  is  becoming  less  and  less 
important,  being  now  so  largely  replaced  by  lead v  arsenate. 

The  writer  wishes,  therefore,  to  present  the  following  proposed  bill 
for  consideration,  and  solicits  comments,  suggestions,  and  expressions 
of  opinion  of  all  parties  interested  in  this  measure.  The  bill  is  based 
on  that  now  in  operation  for  the  control  of  commercial  fertilizers,  and 
is  indeed  the  same  bill  with  only  the  verbal  changes  necessary  to  make 
it  applicable  to  insecticides : 

AN   ACT 

To  Regulate  the  Sale  of  Insecticides,  or  Materials  Used  for  Insecticidal 
Purposes,  and  to  Provide  Penalties  for  the  Infraction  thereof,  and  Means 
for  the  Enforcement  of  the  Act. 

The   People   of   the   State   of   California,    represented   in    Senate   and   Assembly,   do 

enact   as    folloics: 

Section  1.  Every  lot,  parcel,  or  package  of  commercial  insecticides,  or  materials 
to  be  used  for  insecticidal  purposes,  sold,  offered,  or  exposed  for  sale,  within  this 
State,  shall  be  accompanied  by  a  plainly  printed  label,  stating  the  name,  brand,  and 
trade  mark,  if  any  there  be,  under  which  the  insecticide  is  sold,  the  name  and 
address  of  the  manufacturer,  importer,  or  dealer,  the  place  of  manufacture,  and  a 
chemical  analysis,  stating  the  percentages  claimed  to  be  therein,  of  the  substance 
or  substances  alleged  to  have  insecticidal  properties,  specifying  the  form  or  forms 
in  which  each  is  present,  and  the  materials  from  which  all  constituents  of  the 
insecticides  are  derived.  All  analyses  of  substances  for  which  methods  have  been 
agreed  upon  by  the  American  Association  of  Official  Agricultural  Chemists,  are 
to  be  made  by  such  official  methods.  In  the  case  of  those  insecticides  the  selling- 
price  of  which  is  less  than  one  cent  per  pound,  said  label  need  only  give  a  correct 
general  statement  of  the  nature  and  composition   of  the  insecticide   it  accompanies. 

Sec.  2.  The  manufacturer,  importer,  agent  of,  or  dealer  in  any  commercial 
insecticide,  or  materials  used  for  insecticidal  purposes,  the  selling  price  of  which 
to  the  consumer  is  one  cent  (1  cent)  per  pound,  shall,  before  the  same  is  offered  for 
sale,  obtain  a  certificate  of  registration  from  the  secretary  of  the  Board  of  Regents 
of  the  University  of  California,  countersigned  by  the  said  university,  authorizing 
the  sale  of  insecticides  in  this  State,  and  shall  securely  fix  to  each  lot,  parcel,  or 
package  of  insecticide  the  word  "registered,"  with  the  number  of  registry.  The 
manufacturer,     importer,     agent,     or     dealer     obtaining     such     registry     shall     pay 


PROPOSED    INSECTICIDE    CONTROL    LAW.  185 

to  the  said  secretary  the  sum  of  fifty  (50)  dollars,  to  be  applied  as  provided  in 
section  eight  of  this  Act ;  such  registration  shall  expire  on  the  thirtieth  day  of 
June  of  the  fiscal  year  for  which  it  was  given ;  provided,  the  provisions  of  this 
section  shall  not  apply  to  any  agent  whose  principals  shall  have  obtained  a  certificate 
of  registration  as  herein  provided.  Every  such  manufacturer,  importer,  agent,  or 
dealer,  who  makes  or  sells,  or  offers  for  sale,  any  such  substances,  under  a  name  or 
brand,  shall  file,  on  or  before  the  first  day  of  July,  in  each  year,  a  statement,  under 
oath,  with  the  Director  of  the  Agricultural  Experiment  Station  of  the  University 
of  California,  stating  such  name  or  brand,  and  stating  the  component  parts,  in 
accordance  with  the  provisions  of  section  one  of  this  Act,  of  the  substances  to  be 
sold,  or  offered  for  sale,  or  manufactured  under  each  such  name  or  brand. 

Sec.  3.  The  said  director  shall  annually,  on  or  before  the  first  day  of  September, 
take  samples  in  accordance  with  the  provisions  of  section  five  hereof,  of  the 
substance  made,  sold,  or  offered  for  sale,  under  every  such  name  or  brand,  and  cause 
analyses  to  be  made  thereof  in  accordance  with  the  provisions  of  section  one  hereof, 
and  said  analyses  may  include  such  other  determinations  as  said  director  may  at 
any  time  deem  advisable.  Dealers  in  or  manufacturers  of  insecticides  must  give 
free  access  to  the  Director  of  the  Agricultural  Experiment  Station,  or  his  duly 
authorized  deputy,  to  all  the  materials  which  they  may  place  on  the  market  for  sale 
in  California.  Whenever  the  analysis  certified  by  the  said  director  shall  show  a 
deficiency  of  not  more  than  five  per  cent  of  the  substance  alleged  to  have  insecticidal 
properties,  the  statement  of  the  manufacturer  or  importer,  as  required  in  section  one 
of  this  Act,  shall  not  be  deemed  to  be  false  in  the  meaning  of  this  Act ;  provided, 
that  this  Act  shall  not  apply  to  sales  of  insecticidal  materials  made  to  a  registered 
manufacturer  of  insecticides  or  to  sales  for  export  outside  of  this  State;  provided 
further,  that  the  said  Director  of  the  Agricultural  Experiment  Station  of  the 
University  of  California  shall,  upon  the  receipt  of  a  sample  of  insecticide,  accom- 
panied with  a  nominal  fee  of  two  (2)  dollars,  furnish  to  the  user  of  said  com- 
mercial insecticide  such  examination  or  analysis  of  the  sample  as  will  substantially
